Taoyuan, for example, is a lonely branch.
When you explain that you have three brothers, it can be interpreted as: they are all good (or bad), and only you are bad (or good).
When you say there are only two brothers, it can be interpreted as: there should be three brothers, and the other "loneliness" is gone.
When you say there is only one brother, it can be understood as: there should be three, but the result is "lonely" and becomes one.
Therefore, there is no need to pursue such words. (including those won by lottery)
